I don't think this needs to be something that varies by OS version.

If you say setting CPP is not necessary, and will not result in more  
ports trying to use "cpp" or "gcc", then how about we just rename  
configure.cpp to configure.rawcpp (so MacPorts sets RAWCPP and not  
CPP)? We would need to handle the existing ports that use  
configure.cpp carefully but long-term does this sound like an ok plan?
